Unveiling the Hidden Bat Diversity of a Neotropical Montane Forest
Mountain environments, characterized by high levels of endemism, are at risk of experiencing significant biodiversity loss due to current trends in global warming. While many acknowledge their importance and vulnerability, ...
When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor
For species characterized by philopatry of both sexes, mate selection represents an important behaviour for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here, we present evidence of male ...
Repeatability in the contact calling system of Spix's disc-winged bat (Thyroptera tricolor)
Spix's disc-winged bat (Thyroptera tricolor) forms cohesive groups despite using an extremely ephemeral roost, partly due to the use of two acoustic signals that help individuals locate roost sites and group embers. While ...
Effects of roost specialization on extinction risk in bats
Los Efectos de la Especializacion de Dormidero sobre el Riesgo de Extinción de Murciélagos
Understanding causes and consequences of ecological specialization is of major concern in conservation. Specialist species are particularly vulnerable to human activities. If their food or habitats are depleted or lost, ...
Sound amplification by means of a horn-like roosting structure in Spix's disc-winged bat
While sound is a signal modality widely used by many animals, it is very susceptible to attenuation, hampering effective long-distance communication. A strategy to minimize sound attenuation that has been historically used ...
Variation in echolocation call frequencies in two species of free-tailed bats according to temperature and humidity
Bats can actively adjust their echolocation signals to specific habitats and tasks, yet it is not known if bats also modify their calls to decrease atmospheric attenuation. Here the authors test the hypothesis that individuals ...
This is a slideshow produced for the 10th International Congress on the Systematics and Ecology of Myxomycetes, held in the city of Turrialba (UCR, Sede del Atlántico) in February 2020.
Contact calling in context: intra- and intergroup variation in vocalization rates depend on a call’s function
To maintain group cohesion while coordinating group movements, individuals might use signals to advertise the location of a route, their intention to initiate movements, or their position at a given time. In highly mobile ...
Proceedings of the ICSEM10 Costa Rica
Este documento corresponde con la memoria completa del X Congreso Internacional sobre Sistemática y Ecología de Mixomicetes (ICSEM10) celebrado en la Sede del Atlántico de la Universidad de Costa Rica entre el 25 y el 28 ...
